Scientific paper

While the SDSS spectroscopic survey is intended primarily to obtain redshifts of galaxies and quasars, spectra of thousands of stars are also being obtained. Some of these stars are intended spectroscopic targets: there are standards of various kinds, stars targeted for stellar science and/or Galactic structure science, and objects that are assigned spectroscopic fibers due to their unusual location in 5-color space. We present a number of spectra showing the spectral sequence of early through late stellar types. This sequence demonstrates the coverage, resolution, and spectral classification capabilities of the SDSS spectrographs and shows the promise of a stellar spectral atlas of SDSS spectra, currently under construction. We also show spectra of unusual objects. Many of these are of relatively rare, though previously classified, stellar types or binary systems. But some of the more unusual spectra show stellar features that have defied classification to date.
